To all whom, it 77mg/ concern:

Be itknown that I, WILLIAM E. TALLooT, of Groton Landing, in the county of Vilestchester and State of New York, have invented a new and Improved Brick-Machine, of which the following is a full, clear, and exact description.

This invention relates to brick-making machines, the main objects of the invention being as follows: to provide an improved mechanism for starting, driving, and stopping the operating portions of the brickmaking machine, to improve the construction of the pressbox by providing` the same with yieldinglymounted traps that are held closed by adj ustable springs, to provide for the adjustment ol the plunger even at times when the machine is in operation, and to provide for the auto matic return of the safetyslide arranged in connection with the feed-table at times when said slide is forced forward by the operation of its actuating-cam.

Although I have enumerated certain spe cie objects, I wish it to be distinctly understood that many other objects are aimed at and accomplished by the novel constructions and combinations illustrated in the drawings and to be hereinafter described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of my improved brick-machine, the clutches and connections upon thedriving-shaft being shown in section. Fig. 2 is an enlarged detail View of a portion of the front ofthe pressbox. Fig. 3 is an enlar-ged detail view in section, taken through the main door and trapsupporting bar of the pressbox. Fig. 4 is a side elevation of the machine, parts being broken away and parts being shown in section. Fig. his a detail view of the plunger-adj usting attachment, a portion of the case being broken away. Fig. 6 is a plan view of the machine, the upper crossbar, driving-shaft, and a portion of the main gear being broken away to disclose the arrangement of the plungeroperating eccentric, the universai joint arranged in connection (No model.)

with the plungcr-pitman or connecting-rod being shown in section. Fig. 7 is a detail View of the head of the shank of one of the clutclr clamping bolts and its connections. Fig. 8 is a sectional view taken on line w of Fig. 7. Fig. 9 is an enlarged plan view ofa portion of the moldtable. Fig. 10 is a sectional View taken on line x x of Fig. 9. Fig. 11 is a central sectional elevation of a portion of the maM chine; and Fig. 12 is an enlarged detail View, in partial section, of a portion ofthe friction clutch.

In the drawings above referred to, 1() represents the base-frame of the machine, above the main portion of which frame 10 the mudeylinder 11 is mounted, said cylinder being directly supported by a semi-cylindrical base, 12, which carries the bottom 13 of the mudcyiinder 11. Vertical posts or standards 14 and 15 are connected to opposite sides of the cylinder 11, said posts Joeing connected by a cross-bar, 16, which is rigidly connected to a bracket, 17 by braces 1S. The posts or standards 14 and 15 are provided with bearings for the drivingvshaft 20, upon which shaft there is mounted a friction-clutch, 30, of which the section 21 rides upon a feather, 22, that is formed upon the shaft 20. This section 21 is formed with an undercut groove, 23, and with a flat or conical bearing-face, 24. The other section of the clutch is shown at 25, and consists of a disk that is made integral with a sleeve,26, which rests loosely about the shaft 20.

The section 25 is formed with two or more bosses or projections, 27, that are centrally apertured to receive the Shanks 28 ofthe clntchclamping bolts 29, the heads of these bolts 29 riding in the undercut groove 23 ofthe clutcli section 21. The extending ends ofthe shanks 28 are formed with slots 31, in which there are placed trunnioncd blocks 32, said blocks being adjustable toward the head of the bolt by means of set-screws 3S, which engage with threaded apertures that are formed in the eX- treme ends of the shanks 28.

To the trunnions 34 of the blocks 32, I conneet arm-sections 35,which sections are united by a bolt, 36, and the ends of each pair ol" these armsections are apertured in order that they maybe engaged by a bolt, 2,which passes IOO through the arms of a link, 37, the opposite ends of which links are connected to a sleeve, 38, said sleeve being mounted upon the sleeve 26 and being formed with a groove, 39, that is entered by the bifurcated end of an operating-lever, 40, said lever being pivotally connected to a bracket, 4.1, that is secured to the vertical post or standard l5.

The arm-sections are formed with cambearing faces 3, and between said cams and the faces of the projections 27, I place wearplates 42,7the arrangement being such thatif the lever be thrown in the direction of the arrow shown in connection therewith the two clutch-sections will be iirmly clamped together, for such movement of the lever 40 will force the cams 3 to bear hard against the wearplates 42, and the bearing-faces of the two 'clutch-sections will be firmly clamped together, imparting motion to the operatingshaft.

The sleeve 26 is formed with a clutch-section, 5, which engages with another clutchsection, 6, that is formed upon a bevel-pinion, 43, said pinion being held in engagement with the sleeve 26 by means of a collar, 44, that is held to the shaft 20 in advance of the pinion by a set-screw, 45, a second collar, 44, being arranged in connection with the clutch-section 21. The pinion 43 engages with a large bevel-gear, 46, that is carried by the main operating-shaft 47, said shaft being stepped upon the bottom plate, 13, and being guided by a bearing formed in the cross-bar 16.

Below the cross-bar 16 the shaft 47 carries an eccentric, 48, upon which there is mounted a sectional eccentric-strap, 49, which strap is connected to a bell-crank rocker, 50, by means of a connecting-rod, 51, said rod being pivotally mounted at one end between jaws 52, that are formed upon the strap 49, while at the other end the rod is connected to the rocker by means ot' a universal joint, 53. Between the outwardly-extending arms of the bell-crank rocker 50, I mount a pitman or connecting-rod, 54, the lower end of which rod is bifurcated and carries a pin or bolt, 55, which rides in slots 56, that are formed in the side walls of a case, 57, the lower end of said case being connected to the plunger 58, which plunger is mounted to reciprocate in the pressboX 60, thc case being guided by ways 59, that are secured to the peripheral face of the cylinder 11.

Within the case 57, I pivotally mount an adjuster, 61, said adjuster being formed with a number of bearing-faces, 62, which bearingfaces recede step by step from the pivotal connection of the adjuster. Upon the extending portion ofthe adjuster th ere is formed ahandle, 63, and the upper face of the adjuster is circular, being formed upon a curve that is concentric with the axis of the pivot or bolt upon which the adjuster is mounted, and this circular or curved face, which is shown at 64, is formed with recesses or notches 65, that are engaged by a spring-catch, 66, that is carried assess by the case 57, the arrangement being such that bygrasping the handle 63 and forcing the adjuster inward the pin will be caused to bear. upon one of the steps 62, that is more remote from the pivotal connection of the adjuster than the step against which the pin or bolt 55 would bear when the adjuster was pulled outward in the direction of the arrow shown in Fig. 5. In this way it will be seen that the downward throw of the plunger 58 may be so adjusted that the plunger will act properly irrespective of the character of the clay within the feed-box.

The shaft 47 is provided, as usual, with a series of spirally-arranged radial arms, 70,and below these arms shoes 71 are formed upon the shaft, wiper-plates 72 being bolted to the shoes, which wiper-plates act to force the mud through the opening 73 and into the pressbox 60.

The front wall of the upper portion of the press-box 60 consists of a door, 74, said door being hinged at one end of the press-boX-and being held to place at the other by a swinging bolt, 75. Beneath the door 74 there is a crossbar, 76, which is formed with an opening, 77, for each of the molds or forms that are placed upon the moldtable beneath the press-box, and at each side of these openings 77 there are recesses 78, in which there rest the trunnions 79 of traps 80, the trunnions of said traps being` held to place by plates 81, that are secured to the bar 76 and arranged to overlap the recesses v78, thus serving to hold the trunnons within the recesses. The traps 80 are formed with side lugs or projections,82, which bear against the bar 76 at either side of the opening 77, and from the longitudinal center of each trap there isa forwardly-extending boss or projection, 83, which is formed with a central channel, upon either side of which there are ribs 84.

Flat springs 85, formed with curved lower ends. are held to the door 74 by set-screws 86, which engage with apertured bosses 87, between which bosses and the door the springs pass. The lower curved ends of the springs 85 rest in the grooves or channels between the ribs 84, the springs thus acting to hold the trapsin a closed position with a yielding pressure, which pressure may be increased by lowering the springs or diminished by raising the springs. The action of this spring tends to hold the trap open after the trap passes a horizontal position, but will close it from any point below a horizontal position.

Beneath the mold-table there is mounted a frame, 90, the side edges of which slide in grooves formed in the inner faces of the frame 10. To the upper side of the rear end of this frame are attached two bars, 91, which extend upward and forward above the table 11a, said table being longitudinally slotted to provide for the movement of these bars. To the forward ends of the bars there is attached a crossbar, 92.

Within the frame 90 there is mounteda bar,

IOC

IIO

accesa 94, upon which there is mounted a roller, 95, and the forward end of this bar normally engages a shoulder formed upon a lever, 9G, that is pivotally connected to a support, 97, that is carried by the frame 90. A spring-catch, 98, engages the forward end of the lever 96, and a spring, 99, arranged as best shown in Fie. 1l, acts to throw the lever into engagement with this catch. Io the bar 94, I connect a weight, 100, by means ofa cord or chain, 101, which passes over a sheave, 102.

The shaft 47 carries two cams, 103 and 104, the cam 103 being arranged to bear against the roller 95 as the shaftis revolved,while the cam 104 is arranged to bear against a downwardly-extending projection, 105, that is carried by the frame 90, the arrangement being such that as the shaft 47 is revolved, as above stated, the frame 90 will be forced forward by the action of the caln 103 and backward by the action of the cam 104; but should any obstruction be encountered the tension of the springcatch 98 and of thespriug 99 will be overcome, and he bar 94 will be forced forward without moving the frame 90.

In order that the molds, which, it will be understood, are placed upon the table 11 beneath the press-box 00, may be forced forward with a minimum amount of friction, I mount rollers 106 in boxes 107, that are supported by flanges 108, the upper peripheral faces of the rollers being just above the level of the table 11, liners, as 109, being employed to adjust the bearings 107 of the rollers 10G, while the table 11, which carries the rollers, is adjusted by means of set-screws 110.

I am aware that it is not new to opcratethe press-box plunger by means of a verticallyreciprocating pitman connected to a bellcrank lever` operated by a rod having a strap at its opposite end surrounding an eccentric mounted on a shaft parallel with the main shaft. The throw of the plunger was regulated by a swinging stepped adjuster having a cross'bar riding over au are and held in its adjusted position by means of a locking-pin entering any one of a series of apertures in the top of the arc. I do not claim such prior construe tion as of my invention.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
